Disney's 2013 animated hit Frozen continues with Frozen Fever, an animated short that will play before the live action movie Cinderella when it opens on March 13.

The story is set on the date of Anna's 19th birthday. Elsa, Kristoff and Olaf plan to give her the coolest birthday bash ever, but Elsa gets struck with colds and her powers run the risk of going on an icy fever as well.

"Frozen 2" is now official

03/20/2015 Update

And just last week, Disney officially announced their plans to produce an official full-length sequel to the movie that has been a hit since its premiere in November 22, 2013.

John Lasseter, chief creative officer of Walt Disney and Pixar Animation Studios, made the announcement with Disney chief Bob Iger and Josh Gad, the voice of Olaf. The first film's directors Jennifer Lee and Chris Buck will develop the project with Peter del Vecho for Walt Disney Animation Studios. The sequel's release date and other details are still--again, pardon the pun--on ice.
